When I issue an IMAP copy command using the wrong UID, the server gives an "OK No messages copied" response.
This seems like the wrong response to me. If the UID doesn't exist, then it should respond with a "No" response - maybe something like "NO - copy error: bad UID"
I believe "OK No messages copied" would only be a suitable response if the email with the supplied UID had already been known to be copied successfully. I am using dovecot 1.2.9 - has this been fixed in newer versions of dovecot?
Dovecot's behavior is correct. This (or things related to this) has been discussed in IMAP protocol mailing list. Basically it's not an error to use nonexistent UIDs. If you want details, ask in IMAP protocol ml and someone will probably explain.
